Saturday's UFC 153 lineup set with two Facebook prelims, Gonzaga off card

The pay-per-view event, which takes place in Rio de Janeiro at HSBC Arena, features a three-round light-heavyweight headliner between middleweight champion Anderson Silva and Stephan Bonnar.

The lineup includes prelims on FX and Facebook.

Originally scheduled to include 13 bouts, the UFC 153 fight card now has just 12. This past week, Geronimo dos Santos (31-14 MMA, 0-0 UFC) dropped off the card for undisclosed reasons, and his opponent, heavyweight Gabriel Gonzaga (13-6 MMA, 8-5 UFC), also has been scratched. The bout initially was expected to be part of the FX-televised preliminary card.

UFC women’s bantamweight champion Ronda Rousey is probably the greatest female fighter on the planet, which is a tremendous feat. So why are we seemingly so obsessed with arguing about whether she could beat up men?
